+This document lists various terms used in DBIx::Class and attempts to

 =head1 TERMS
 
+=head2 DB schema
+
+Refers to a single physical schema within an RDBMS. Synonymous with the terms
+'database', for MySQL; and 'schema', for most other RDBMS(s).
+
+In other words, it's the 'xyz' _thing_ you're connecting to when using any of
+the following L<DSN|DBI/connect>(s):
+
+  dbi:DriverName:xyz@hostname:port
+  dbi:DriverName:database=xyz;host=hostname;port=port
+
+=head2 Inflation
+
+The act of turning database row data into objects in
+language-space. DBIx::Class further allows you to inflate your data
+into perl objects which more usefully represent their contents. For
+example: L<DBIx::Class::InflateColumn::DateTime> for datetime or
+timestamp column data.
+
+=head2 Join
+
+This is an SQL keyword that gets mentioned a lot. It is used to fetch
+data from more than one table at once, by C<join>ing the tables on
+fields where they have common data.
+
+=head2 Normalisation
+
+A normalised database is a sane database. Each table contains only
+data belonging to one concept, related tables refer to the key field
+or fields of each other. Some links to webpages about normalisation
+can be found in L<DBIx::Class::Manual::FAQ|the FAQ>.
+
 =head2 ORM
 
+Object-relational mapping, or Object-relationship modelling. Either
+way it's a method of mapping the contents of database tables (rows),
+to objects in programming-language-space. DBIx::Class is an ORM.
+
+=head2 Relationship
+
+In DBIx::Class a relationship defines the connection between exactly
+two tables. The relationship condition lists the columns in each table
+that contain the same values. It is used to output an SQL JOIN
+condition between the tables.
+
+=head2 Relationship bridge
+
+A relationship bridge, such as C<many_to_many> defines an accessor to
+retrieve row contents across multiple relationships.
+
 =head2 ResultSet
 
 This is an object representing a set of data. It can either be an
